Hi Peter,

Perhpas you were getting responses from a BIND server that has/had
"minimal-responses" set to "yes". Enabling this option in BIND makes it
emit record in the authority section only for responses that need it,
like delegations and negative responses.

I do get records in the authority section for that query, so either ISC
has reconfigured something, or we're talking to different servers.

Regards,
Anand
